Texting Has Spoilt Grammar

Iam an indian and obviously English isnt my mothertongue. But somehow i have always had a passion for English. I spoke better than my peers and also wrote with lesser flaws.No wonder,i became an english teacher after doing my degrees.It pains me to see that writing in wrong grammar is considered cool these days. The main culprit is texting via the mobile phone. I must admit that i too use shorter forms of all words during texting but saneness prevails over me in other situations. Students have started using texting language in their examination papers ,here and there."what" is written as wat.."yes" is written as S .The list is endless. A fifth grader is able to write better english than a high school kid.
wat r the ills of smokin.writ in dtail
Can you believe that we had a student who wrote like this in his exam?

I have recently moved to an unlimited text message plan so I do much more of that message system but still feel it is so wrong to "u n ur" for "you and your" even when I am replying to someone who does do that. I have enough trouble with fat finger typos, I don't need text spelling and grammar, too, to make what I write unreadable.

I USUALLY USE ABBREVIATED WORDS DURING TEXTING..... BUT DURING EXAMS AND OTHER FORMAL ACTIVITIES, ILL MAKE SURE OF MY SPELLING.... I EVEN ASKED MY FRIENDS TO CORRECT MY SPELLING IN SOME SIMPLE WORDS. CONFUSION TO SOME SIMPLE WORDS (like sac instead of sack) IS THE RESULT OF BEING A TEXT ADDICT.

Does it get on your nerves when someone uses bad grammar and they think its normal?
For example:
"Don't you..." Meaning "Do not you..."
"Why can't I..." Meaning "Why cannot I..."
"Isn't it..." Meaning "Is not it..."
As you can see, these are all compound words. I find them...
